Help! I can't add my email account to Email API authorized senders.

[Kai Zhou]

I am trying to set up the email sending feature in google app engine. I want to send emails through the address associates with my domain admin@[mydomain].com. I try to edit the setting in the follow page:

But when I click "save", nothing happens. And when I refresh the page, the email I add just disappears. Does anyone have the same issue? Does anybody know what is going on?

If you hover over the question mark besides 'Email API authorized senders', it says 'In most cases, users can only add themselves to this list'. Try to login as that account and add the account.

But isn't that too limited? That way I can only send email with one address.

This is related to the addition of the email addresses under ‘Email API authorized senders’ and not application sending emails. Once an email address is added, the application can send email on behalf of the users listed.
